Opheodesoma Spectabilis
''Opheodesoma spectabilis'' is a synaptid sea cucumber in the Indo-Pacific that can be locally very abundant. Description With their flexible, wormlike bodies and mouth surrounded by tentacles ''Opheodesoma spectabilis'' varies in color. From a shade of gray when above water, to a rich chocolate brown or "bloodsucker" red when below water. Biology As sea cucumbers most commonly do, the Opheodesoma are invertebrates that start their life cycle as Planktotrophic larvae. They then grow into cylinder-shaped doliolaria who metamorphose into the juvenile opheodesoma spectabilis you often see today. Distribution and habitat ''Opheodesoma spectabilis'' is located in subtropical and tropical areas such as New Caledonia, Hawaii, the Indo-Pacific, East Africa, and Guam. Generally found at the bottom of the ocean floor within the sand, crumble, shells, and brown algae called Sargassum ''Sargassum'' is a genus of brown (class Phaeophyceae) macroalgae (seaweed) in the order Fuca ...

Synaptidae
Synaptidae is a family of sea cucumbers that have no tube feet, tentacle ampullae, retractor muscles, respiratory trees, or cuvierian tubules. They also lack radial canals of the water-vascular system, with only the circumoral ring present. Synaptids have elongated bodies, and their size varies significantly from small to quite large. '' Synapta maculata'' grows to two metres in length. They are quite active, moving by means of waves of peristaltic contractions. Their tegument is somewhat sticky because of the anchor-like spicules that project through the skin.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
